The'upper l 6 me Ian Y ma Pelee o eevlcee 50 edge of the deflector 9 marked byvthe numeral nozzle Bl hasoutwardly extended branches 6?, it, is located slightlybelow the upperedge of the h h the branches 62 being w for neck 2. l The forward edges5 of the d rotation in the, inner ends of the parts t6 of the flector 9are oppositely disposed, and are located Outlet membhr the constructlonbang such, in a plane passing through the axis of theboss 3. vthat e n lbe swung up an d wn, 55

of Fig. 1. The inner ends of the parts 56 of the outlet member 4!], andthe terminal portions of the branches 62 of the nozzle 51, are suppliedwith cooperating recesses 63, wherein is mounted the packing 5E),hereinbefore referred to. The packing is of annular form, and issustained in its annular form by a perforated metal ring 64,

located. within the packing and received in the cooperating recesses 63,as Fig. 2 will show. A nipple 65 is mounted in each inner end portion ofthe parts 55 of the outlet member 40. The bore of the nipple t5communicates with a duct 68 in the inner end of the member 56, andleading to the cooperating recesses 63.

I Noting Fig. 2 of the drawings, it will be seen that the passagesafforded in the parts 6| and 56 of the outlet member All are of greatestcross sectional area adjacent to the sleeve 42. of Fig. 1.

Thence, they taper gradually and fairly, to the place where the branches52 of the nozzle 6i merge into the outlet member of the nozzle. Thegradual taper of the passages through the outlet'member M and thebranches 62 of the nozzle tends'to reduce friction and resistance to thepassage of water to the nozzle 6 I, and the volume of waterclischargedis increased, velocity being increased also. It may be noted here,incidentally, }th'at the side portions of the outlet member '30extendoutwardly to such an extent that they form convenient handles forcarrying the device about. Y I

It can be ascertained from Fig. 1 that the outlet member 48 slopesbackwardly and downwardly somewhat sharply. The back-kick of the -waterpassing through the nozzle 6| thus is brought low, and increasedstability results,

there being a decreased tendency to tip the article over, due to theback-kick of the passing water. This consideration is especiallyvaluable if the nozzle Bl happens to be so disposed that it isdischarging. at an angle that, otherwise,

would tend to produce the undesirable result referred to.

Comparing Figs. 1 and 2, where the forward walls of the branches "52 ofthe nozzle 6| join,

there is located an integral segment 51, extended by collars and pinsl3, or any equivalent structhe body l.

the Valve 29 of Fig. l closes automatically, and

. claimed is:

tures. Acrank 14 (or something else) on the upper end of the shaft ll,constitutes means whereby the shaft may be rotated. Noting Fig. 2,itwill be observed that the opening 68 that extends vertically through theoutlet member 60, afiords room for the segment 5?, the Worm it, theshaft H, and the brackets 12. The stop 69 on the segment 57 (Fig. 1) isadapted to co operate with the lower end of the worm ill on the shaft H,and, thus, the downward swinging movement of the nozzle 5! is limited tothe dotted line position of Fig. 1.

The advantages of the device are found mostly in its structuralfeatures, and have been set forth in the foregoing description. Theyneed not be repeated at this place.

As to general operation, the water enters by way of the inlets l5 andleaves by way of the nozzle Bl, the nozzle being adjusted to differentangles by the simple train of parts including the shaft H, the worm l5and the segment 57.

The inlets l6 afforda means whereby several pieces of hose may be madeto discharge into If any piece of hose is removed,

is held closed by the back pressure within the body I, created bywater'delivered through. the pieces of hose which remain assembled withthe body.

Having thus described the invention, what is 1. In a device of the classdescribed, a body having an inlet, a loop-shaped outlet member, theforward portion of which is intermediately connected to the body, incommunicating relation therewith, a nozzle'having opposltely'disposedlateral branches rotatably mounted in the rear portions of the outletmember, the branches and the rear portion of the outlet member havinginternal, communicating recesses, an annular packing in the recesses, anannular sustaining ring on the packing, and a fixed nipple having a boredischarging'into the recesses.

2. In a device of the class described, a hollow body having an inlet,and provided on its bottom with an upstanding boss, a nozzle-partmounted on the body, a post attaching the nozzle'part to the body andassembled with the boss, there being apassage through the body andthrough the nozzle-part, the passage making a turn within the body,between the inlet and the nozzle part, a curved deflector renewablymounted in the body at said turn, and having. a .notchxreceivingxtheboss, and means for attaching-the deflector detachably to the body.
